Four-time Verizon IndyCar Series champion Scott Dixon drives his Honda around Texas Motor Speedway as he took practice laps in the Dallara IR12 chassis that is outfitted with a new aero kit in Fort Worth, Texas, Monday, October 23, 2017. The aero kit, including a new rear wing and no rear wheel guards, will make the cars safer and increase the ability to pass. The new body style is designed to reduce turbulence and make it easier for cars to follow and pass each other on the track. (Tom Fox/The Dallas Morning News)
